There have been only two major power generation projects, Tarbela and Mangla Dams, which do not produce adequate electricity for the entire country. In the absence of any other mega dam project, it was planned to utilize the downstream flow of the Indus from Ghazi to Barotha and produce electricity at Barotha by the fast current of downstream water. Ghazi Barotha Hydropower Project holds the record for the biggest lined channel in the world.
The channel is some 51.90 kilometers long with a concrete lining and design flow of up to 1,600 cumecs at a water depth of 9 m and a bottom width of 58.4 m. The difference of height between Ghazi and Barotha is 76 metres, which makes the water to flow at the speed of 1,600 cumecs, creating enough pressure to run turbines at Ghazi to generate some 1,450 MW of electricity and an average energy output of 6,600 GWh.
Ghazi Brotha Hydropower Project with a generation capacity of 1,450 MW and an average energy output of 6,600 GWh is a large, renewable and emission-free source of energy towards WAPDA's Vision 2025 goals.
